Loading color corrections from VFB history refreshes IPR renders

When using IPR in RT set as production renderer, loading color corrections from VFB history refreshes the render. This doesn’t happen with IPR in Adv.

Update: It also happens with RT in Active Shade mode.

Hello,

My guess is you are using a V-Ray physical camera? There was an issue that we fixed with it and enabling OCIO color correction that caused a refresh.

Best regards,

Thanks for the reply. I’m actually using Physical Camera, not V-Ray camera. I’m also not using any OCIO, LUT or ICC color corrections, just Exposure, White Balance and Curve.

I’ve just run a test with Max 2016 SP3 and V-Ray 3.50.04 and I can confirm that loading presets for Exposure, White Balance and Curve don’t restart IPR rendering.
I am going to update 3dsMax to SP4 and will repeat the same test, meanwhile would it be possible to send us the scene you are working on for investigation?

Works fine whit SP4 as well, here is a video from my tests here:

Hm… strange, appears to be working normally in your videos. Ok, I’ve just sent the scene to support along with a couple of VRIMG files so you can load color corrections from them in VFB.

I just wanted to update you on this issue. I got an email reply from support asking me to try with the latest nightly. I did and after some tests it seems to be fixed! Hopefully the fix makes it in the new update. :slight_smile:
